Interior Space and Exhibition Design Grand Gate Hiroshima Restaurant by Daisuke Takamiya Grand Gate Hiroshima is a food hall located on the second floor of the Hiroshima JP Building and connected by pedestrian walkways to Hiroshima station. The 660 square metre space contains six stores arranged in seven areas with an open concept and few partitions. Each shop has its own character, yet the whole forms a unified composition. The layout follows the shape of the Ota River delta and guides visitors through the retail zones. Materials such as terrazzo, resin and shells recall the pebbles, rivers and sea of the region.
